In the end, the existing disaster management So far, there is no uniform classification for this category. Definition of Disaster For operational purposes, the World Health Organization Typical Course of a Disaster defines a disaster as a sudden ecological phenomenon of sufficient magnitude to require external assistance. Another operational definition says that a disaster is any • Communication is disrupted. Disasters usually have an unforeseen, • Difficulty in obtaining a full picture and making serious, and immediate affect on health. A disaster is an occurrence such as hurricane, tornado, storm, flood, high water, wind-driven water, 3,4 Disaster Assessment tidal wave, earthquake, drought, blizzard, pestilence, famine, fire, explosion, volcanic eruption, building Assessment is a crucial management task which collapse, transportation wreck, or other situation that contributes directly to effective decision-making, causes human suffering or creates human needs that planning and control of the organized response. Classification of Disasters • The needs and priorities for immediate emergency measures to save and sustain the lives of survivors. Depending on their nature, disasters are classified as: • The resources available. The assessment process needs to be continuous is done in the camp/community with the group leaders. In the community/camp Phases in the management of disasters a place is arranged to boil water. There are four essential phases in the management of – Water is stored in three separate containers for disasters: drinking, cooking and washing (bathing and 1. Some General Guidelines are followed5-7 Nutrition and Food Hygiene Camps for temporary shelter for the displaced are – A team of food handlers are appointed. They are organized optimally so that there is equity in distribution being educated for personal hygiene, and food of resources and disease and disability are minimized. In this type of situation facilitates proper distribution of relief aid and health especially infants and children are more prone care. As far as possible, accommodation of the to infectious diseases (due to poor sanitation and persons in the camp is done as family units. In situations where artificial feeding is The initial assessment should be followed up with more detailed assessment during the rehabilitation and recovery phase as shown in the following flow diagram3-5 681 done, feeding is done by cup rather than a bottle emotional and physical pressure, and in conditions and because it is easy to clean/sterilize and the risk of environments, that they might not be familiar with. Sanitary facilities: Adequacy and cleanliness of Management Aspects toilets are ensured. The purpose of a command post is to coordinate activities Proper garbage disposal – Garbage are collected, sorted and disposed off at the disaster site. In order – Cleanliness in and around the camp is to avoid this, a single authority for operations must be maintained by health education and supervision. This role is usually assigned to drugs and records, and do not have access to clinics. The essential functions of a command post are to provide • The psychological impact of trauma on children is a preliminary evaluation of the magnitude of the more severe than in adults, but children are unable disaster, coordinate emergency medical care, delimit the to express their negative thoughts. Policy planners affected area, establish safety measures and a network must play an active role to relieve the psychological of emergency communications, regulate traffic, and set impact on the community. The relief • Infections are common in overcrowded camps: agencies or brigades working at the disaster area should dysentery, acute gastroenteritis, upper respiratory assign a representative to the command post. All staff tract infections, vector borne infections (especially assigned to the command post should wear a badge to dengue and malaria), exanthemata (especially identify themselves clearly. In the absence of a confusion and disorganization in handling victims at a physician, a qualified nurse or paramedic with broad disaster site. Frequently observed problems include situations predesignates a medical authority to this role. This coordinator should be a professional with sufficient authority over the medical and paramedical personnel Potential Risks at the Disaster Site to assign tasks and areas of action. The medical coordinator works closely with the physician responsible Health staff (physicians, paramedics, and rescue squads) for classifying the patients by degree of urgency and with can potentially be at risk for accidents at the scene of the assistant responsible for transportation. Although these risks are not common to all disasters, personnel must be adequately The word triage is of French origin and means selection prepared for safety measures. The concept of triage in a disaster 682 situation means classifying victims in order to assign to a secondary disaster. It is also important to point out that personnel at the disaster site work under high priorities for medical care and transportation. Emergency medical care at these areas is aimed at stabilizing the This concept is based on establishing the urgency of a patient and providing basic care to ensure survival. It differs from Usually, stabilization implies clearing the respiratory tract, daily emergencies where the most serious cases always controlling bleeding, and maintaining circulation. The receive priority care, without consideration for the triage area should be the responsibility of a physician likelihood of survival. Triage actions at the disaster site or, alternatively, a nurse or paramedic with experience include identifying victims, assessing injuries, assigning in mass casualty management and with authority to priorities for care, and stabilizing and transporting victims coordinate emergency care activities at the disaster site. After a rapid medical examination, he assesses the victims and assigns Tagging them the respective priority. The areas should be easily identified methods have been used, such as: marking the victim’s by flags or other means using colors that correspond skin in a visible place; applying piece of adhesive tape to each priority. The purpose of standardized tagging system they are transported according to their assign priority. The complete identification data, or suggest a I priority most popular method is triage cards. This does physical structures, distances, I and the super-saturation not mean that other standardized models cannot be used. Mobile units are costly and their Triage is an ongoing process that begins at the disaster use should depend on the performance and self-reliance site and continues until the patient enters the hospital of the personnel, equipment and supplies. The victim’s survival depends on the effectiveness and timeliness of this activity. Essential supplies should be duly classified if they are trapped or under rubble in difficult to reach and distributed in clearly identified and easy-to-transport places, or when they are exposed to secondary risks, boxes. The boxes should contain the following basic such as fires or toxic substance leaks. Usually, complex supplies and equipment: rescue tasks are not within the scope of health teams. Depending on the magnitude of the disaster and the • Basic instruments for minor surgery and splints. A triage area is the area where victims are placed • Portable lighting equipment, including flashlights. Health problems in temporary shelter: When situations has broadened which now include industrial, the affected community is shifted temporarily nuclear as well as biological disasters.

In the picture of an atom that we present there are energies that are not available for electrons to reside in.
